==Overview ==

==Overview ==

The ''Trichuris'' worms, part of the Trichuroidea superfamily, are so called due to their characteristic whip like structure. They have a broad posterior end tapering to a long and narrow neck which is inserted into the caecal mucosa. They have a direct life cycle, moving directly into the definitive host from the infective L1 egg stage. Once ingested the larva is freed from the egg casing due to digestion of the plugs at either end of the egg. The larvae then form mucosal nodules in which to develop before emerging into the lumen of the large intestine and caecum of the host.

Adult worms bury the thin anterior into the intestinal mucosa and feeds on tissue secretions from the damaged cells rather than blood. The invasion of the worm causes [[Eosinophilia|eosinophilia]] in the host animal as it mounts an immune response against the worm. The most common clinical signs are:
